Low Vision Rehabilitation for Age-Related Macular Degeneration
An 80-year-old female with bilateral age-related macular degeneration (AMD) presents for a low vision evaluation. Her best-corrected visual acuity is 20/200 in the right eye and 20/400 in the left eye. She reports difficulty reading, watching television, and recognizing faces. She lives alone and enjoys reading novels. She has a supportive family but is reluctant to ask for help. She uses a magnifying glass occasionally but finds it inadequate. She is otherwise healthy and takes no medications. She is interested in any device that can help her read for extended periods.
1. What low vision devices would you recommend and why?
Read the worked answer
For reading, a high-power stand magnifier with a built-in light and a large field of view would be beneficial. Alternatively, a closed-circuit television (CCTV) system provides high magnification and contrast enhancement, allowing extended reading with less fatigue. Given her desire to read novels for extended periods, a CCTV or a portable electronic magnifier (e.g., a tablet with magnification software) would be ideal. For watching television, a telescope or a magnified screen could help, but she may prefer to sit closer. For recognizing faces, a handheld telescope or a face-to-face magnifier could be used. The choice depends on her motivation, dexterity, and budget. She should be trained on the devices and given trial periods. Also, consider non-optical aids: proper lighting, large-print books, and contrast enhancement. A multidisciplinary approach with a low vision therapist is recommended. The goal is to improve her quality of life and independence.
2. How would you counsel the patient regarding her reluctance to ask for help and her overall management?
Read the worked answer
The patient's reluctance to ask for help may stem from a desire for independence. Counsel her that using low vision devices and accepting help are tools to maintain independence, not signs of weakness. Discuss her goals and priorities. Involve family in a supportive way, perhaps by inviting them to a session to learn about her needs. Educate her about AMD and the importance of regular eye exams, smoking cessation, and AREDS2 supplements if appropriate. Refer her to a low vision rehabilitation service, occupational therapist, and support groups. Address any safety concerns at home (e.g., lighting, fall prevention). Emphasize that many people benefit from these resources. Follow up to ensure she is using the devices correctly and to adjust the plan as needed. Document the counseling and referrals.
